CONCRETE--BUILDING FORM.

Application filed .Tanuaiy 20, 1923. Serial No. 613,911.

To all whom it may concern:

Be it known that I, OLEY G. NIoHoLAs, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new andusetul Improvements in Concrete- BuildingForms; and I do hereby declare the following to be a full, clear, and. exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to forms or molds for use in'the construction of concrete buildings, and is particularly an improvement over the concrete building form disclosed in my'Patent No. 1,873,523, granted April 5, 1921.

It is the object of the invention to improve the construction of and manner of assembly of the outer and inner sections of the form, whereby to enhance the efliciency and utility of the form.

With the foregoing and other objects in. view, which willbeapparent as the description proceeds, the invention resides in the construction and arrangement of parts, as hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed, without departing from the spirit or" the invention.

The invention is illustrated in the accompanying drawings, wherein- Figure 1 is an exterior elevation of a tragrnentary portion of the improved form, a

portion of the outer sections being broken away to show the inner sections,

Fig. '2 is an interior elevation, partly in section on the line 2-2 of Fig. 3.

Fig. 3 is a horizontal section on the line 3-3 of Fig. 1.

Fig. 4 is a horizontal section, corresponding with Fig. 3, showing the completed wall. The form or mold, which is shown as being used for molding the wall of a build ing, although it can be used for molding floors, ceilings, slabs, or the like, comprises the outer and inner sheet metal sections 11' 1 where they abut other sections or parts,

Said flanges also stifl'en the sections, which have the sheet metal panels within the outlines of the flanges or rims.

The outer sections 11 are of rectangular form, and are disposed in horizontal courses, wlth the sections of the superposed courses in staggered arrangement, and the vertical or end portions of the flanges 13, wherethey abut, are secured together by bolts 15 or other securing means to prevent horizontal separation of the sections. The sections are seated one on the other, and in order to hold the horizontal portions of the flanges 13 togcther, the upper horizontal portions of the flanges 13 are provided with lips 16 bent back over the same in inclined position so as to extend over the lower horizontal portions of the flanges 13 of the sections 11 immediately above; Thus, the edges of thelower horizontal portions of the flanges 13 abut the bends of the lips 16, to prevent the lower portions of the sections 11 from being displaced outwardly, and the horizontal portions of the flanges 13 are thus held assembled without the need of securing means extending through said flanges at the adjacent edges of the courses of sections. The

lips 16 are inclined to shed concrete and other matter dropping thereon, and the edges of said lips 16 abutthe panels of the sections imediately above. The lips 16 have notches 17 bet-ween their ends to accommodate the vertical portions of the flanges 13. and the ends of the lips 16 are also spaced from the endsor vertical portions of the flanges 13, as at 18, to accommodate the vertical portions of the flanges 13 when necessary.

At the corners, as shown in 3, the vertical portions of the flanges 13 of one side abut the panels of the other side and are secured thereto by the bolts or securing elements 15.

The inner sections 12 are rectangular and elongated vertically, and said sections are of V-shaped horizontal cross section, with the halves thereof at an obtuse angle with one another. Such innersections are set on end one on the other, and the end for horizontal portions of the flanges 14 are secured to gether bymeans of bolts or other securing elements 19.

In building up the form, studs or bars 20 of wood or other suitable material are placed upright between the vertical edges of the sections 12, With the vertical portions of the flanges 14C abutting the sides of said bars or studs, and the angles of the sections 12 ex tend toward the outer sections 11. The inner sections and bars are held assembled temporarily by suitable means, such as nails 21 driven through the vertical portions of the flanges 14 into said bars, thereby retaining said bars in place while the form is set up. The bars 20 also have nails or other anchor members 22 extending therefrom into the mold to be embedded in the concrete, whereby to securely anchor said bars in lace, as seen in Fig. 4;, in the finished wall.

In order to secure the outer and inner sections together in spaced relation, stay or tie rods 23 are inserted through apertures provided in the outer and inner sections, and suchrods are located adjacent to the upper horizontal edgesof: the outer sections and at the elbows or angles of the inner sections. Nuts 24 are threaded on the rods 28 to provide seats against which the sections 11 and 12 bear, thereby spacing said sections apart the desired distance, which may be changed by the adjustment of said nuts 24, and wing nuts 25 are threaded on the terminals of said tie rod to clamp the sections against the seats or nuts 24. In this way, the outer and inner sections are secured rigidly together, and by locating the tie rods at the elbows or angles of the inner sections'12, a substantial structure is thus obtained with a minimum number of connee-tions between the outer and inner sections. It will also be noted that the rods 23 being located adjacent to the upper edges of the outer sections 11, will prevent said upper edge portions of the outer sections from being displaced outwardly, while the lower edge portions are prevented from being displaced outwardly by the lips 16 of the outer sections immediately below.

Suitable reenforcing can be provided within the mold, between the outer and inner sections of the form, to be embedded in the wall, and when the grout is poured into the form, it fills the space between the outer and inner sections and embeds portions of the bars 20 which extend into the space of the mold from the sections 12. The reentrant angles formed by the inner sections 12 will provide channels or recesses 31 between the bars or studs 20 at the inner side of the wall 30, as seen in Fig. 4, which extend vertically. .After the concrete has set, the form sections 11 and 12 can be readily removed, to be used again, by

simply removing the wing nuts 25, bolts 15,

15" and 19, and nails 21. The outer and inner sections are thus taken from the wall, leaving the bars 20 anchored to the wall at the ridges between the channels 31, and said studs or bars can be used for nailing orsecuring the lathing or finishing 32 to the wall. The vertical channels 31 will provide continuous vertical dead air chambers or spaces in rear ofthe lathing to serve as heat insulation, the bars 20 and channels 31 spacing the concrete from the lathing or finishing The wall thus formed will require less concrete than if it were of equal thickness throughout, and will possess a high degree of insulation, to prevent the penetration of heat and cold. Furthermore, the bars 20 provide convenient means for the attachment of the lathing which will be entirely out of contact with the concrete. The wall is solid, in that no openings or passages are provided between the outer and inner surfaces of the concrete which require more or less trouble and complication in the construction of forms. The wall, although solid, has the advantages of a hollow wall it not being superior thereto. The form may also be used for they construction of hori zontal slabs for floors, ceilings, and the like, in which event the sections 11 wouldusually be at the top and the sections 12 at the bottom, the bars 20 providing means for the attachment of the ceiling or overhead lathmg.

Having thus describedthe invention, what is claimedas new is.:- i
